Carbon disulfide (CS2) is a toxic, highly flammable substance.
The following thermodynamic data are available
for CS2(l) and CS(g)at 298 K:

(a) Draw the Lewis structure of the molecule. What do you
predict for the bond order of the C¬S bonds? (b) Use the
VSEPR method to predict the structure of the CS2 molecule.
(c) Liquid CS2 burns in O2 with a blue flame, forming
CO2(g) and SO2(g). Write a balanced equation for this reaction.
(d) Using the data in the preceding table and in Appendix
C, calculate ΔH° and ΔG° for the reaction in part (c).

Transcribed: A HP (kJ /mol) AG? (kJ/mol) CS2(1) 89.7 65.3 117.4 67.2 CS2(8)

The answer for part a) is given below. Kindly post the other sub parts as separate question

The Lewis structure of $C{S}_{2}$ can be represented as follows

The number of bonds between the two atoms is known as bond order. In the above structure, there are two bonds are present between the carbon and sulfur. hence the bond order of $C-S$ bond in $C{S}_{2}$ is two.
